Then below stated are seven reasons why you should stay away from sugar.

1. It has no nutrients added to it:

Of course, we can understand your love for dessert but take a close look and you shall recognize that it’s not doing any good to your body. Added sugars like sucrose and high fructose corn syrup contain loads of calories with absolutely zero nutrients present in it. Hence it also called "empty" calories. Though sugar keeps you high in energy but vital nutrients like proteins, essential fats, vitamins or minerals are totally absent in it.

2. Don’t blame fat as sugar is the reason behind the cholesterol and heart disease:

We thought fatty food is the only reason for the increase in the cholesterol levels; however, the new study suggests the culprit be the Sugar.

Studies have shown that large amounts of fructose can raise triglycerides, small, dense LDL and oxidized LDL (very, very bad), raise blood glucose and insulin levels and increase abdominal obesity. There are many observational studies made which have witnessed a strong statistical link between sugar consumption and the risk of heart disease.

3. Sugar and Cancer? Well, this wasn’t expected!

What can be terrifying than this? It is said that insulin is one of the key hormones that regulate this sort of growth. Many scientists now believe that a constant increase in insulin levels can lead to cancer. Well, we don’t intend to scare you but it’s the studies that are showing the facts!

4. Apparently it also overloads your liver:

When consumed sugar, it enters the bloodstream from your digestive tract and gets broken down into glucose and fructose. Glucose is essential for our body if don’t get it from the diet, our body produces it, but fructose, on the other hand, has no significant importance in our body. An adequate amount of fructose doesn’t do that much of harm as it turns to glycogen and gets stored in the liver but too much of fructose can overload your liver forcing the fructose to turn into fat.

5. The relationship between sugar and diabetes:

In a 2013 study published in the journal PLOS ONE, it was found that consumption of 150 calories of sugar on a daily basis can risk a person to type 2 diabetes by 1.1 percent. Food that includes sugar like soda, meat, oils, cereals, high-fiber foods, and oils are all sailing in the same boat. Researchers also found the impact of sugar on diabetes held true regardless of a sedentary lifestyle and alcohol use.

6. Because sugar intake and obesity go hand-in-hand:

Well, this applies to all age groups and we all pretty much know that sugar can likely make one’s body overweight or obese, at times. And what astounded us more was the mention of children in the category of high risk.

7. Highly addictive and leads to massive dopamine release in the brain:

Dopamine is a chemical released from our brain and too much release of this chemical can lead to ADHD, Alzheimer's, Parkinson's, depression, bipolar disorders, binge eating, addiction, gambling, and schizophrenia.

Like abusive drugs, the intake of sugar causes dopamine in release towards the center of the brain. Sugar and junk foods usually lead to massive dopamine release and hence our elders tell us to stay away from junk.
